Strange behavior (kind of long)

Hi everyone,
My main question is: should I be worried that my rats spend their time
either fighting, harassing each other constantly, or sleeping in
separate parts of the cage?
Some background. Last June I adopted 2 male rats from a local breeder.
They are brothers. However, they rarely ever sleep together and in the
past few months, have really started to fight pretty intensely. No
bloodshed though, so I've just continued to observe them. A couple of
months ago, I rescued a young female rat from a snake tank. I was
originally going to give her up to the humane society but she was a
total darling and curled up on my shoulder and slept there on the car
ride home. So I decided to keep her. In order to have them all together
in one cage, I started quarantine and made an appointment with my vet
to have her spayed (please don't fixate on spaying). I dropped her off,
then get a phone call from them saying that my female rat was actually
a male rat with undescended testicles. Imagine my shock. So after the 2
week quarantine, I started slow introductions. The boys seemed awfully
interested in sniffing the new rat's tail and chasing it around, but I
researched it online and it seemed within the realm of normalcy. The
second time I did introductions, there was definite aggressive chasing.
Then they both proceeded to mount her. Yes...her. I immediately
separated them, brought her back to the vet and had her spayed (please
don't fixate on vet mistakes either). After a week or so, I started
introductions again. They seemed to get along well. So then I finally
moved her into the main cage. For about 4 days now, the boys have done
nothing but try to chase, harass, and mount her, or fight each other
like usual. As a precaution, I had already put a couple of hidey-holes
that were only big enough for her to fit through the opening so that
she would have somewhere to hide if they got too aggressive. However,
she is much more active then the boys, so she only stays in the
hideouts long enough for them to wander away, then she comes out and
the chase starts all over again. The boys sleep in different corners of
the bottom of the cage (I also find that very odd) and she sleeps in a
hideout loft that only she can reach. Is there no hope of them getting
along? Are they only chasing her because they remember mounting her
successfully at one time? If so, there probably isn't anything I can do
except hope they forget. I apologize for being so long winded and I
appreciate any advice.
Thank you!

With your two boys still intact, I imagine that they are just reacting
like any ordinary male rat would.  Their priorities would be defending
their turf and finding mates. Castrating will greatly reduce these
behaviours. Would you be able to get the two males castrated? Once
their hormones settle they will be less interested in mounting her and
less territorial.

I was actually interested in Tardak, the chemical castration, because
I'm not completely convinced that it is all hormonal. Even before the
boys started seriously fighting, they weren't the best of friends. The
bigger one (Euclid) is somewhat jumpy but more accepting of handling,
whereas the smaller one (Ptolemy) has always been a bit nippy and bossy
and less likely to come when called. I don't want to castrate either of
them if it isn't going to help as I am not certain how experienced the
vet is with neuters on rats (the female spay is supposed to be just
like a cat, so I had a little more confidence). There is also the worry
that if it doesn't calm their aggression, they would hurt each other
during the healing period, since separating them could also prove
problematic (I had read an article about aggressive/alpha rats being
killed when returning to a colony after an illness/injury because of
perceived weakness). Has anyone had any experience with the chemical
castration?

Not sure where you read your article, but I've never heard of a rat
killing another rat after returning to the colony.If the separation is a
long one, then intros would be needed but if it's just a day, usually
that's all it takes for recovery of a neuter, then it's just pop back in
 the cage.
I've had a few males neutered and no problems putting them back in the
cage.
But... I would give them some time first to see if they will settle down
with the girl. It usually takes a week or two before the males realize
that she won't give 'em any. And then they can start the bonding process. :)
I haven't heard about Tardak, but I have heard a lady claiming that
Lupron helped her rat become less aggressive.
But before you do anything, I would give them some time first.

Heheh...I didn't realize the boys were going to be that persistent. I
have no problem giving them time to sort themselves out. As long as
they don't hurt her or each other, I'll guess I'll see how it goes. I
hadn't ever seen these behaviors in my previous pair of boys, so I was
just really concerned. Being as they were from someone who breeds for
temperament, I had expected them to be much more mellow. My other boys
never fought (at least that I ever saw). Although in retrospect, my
previous boys's scrotal sacks never hung out like these new boys do
(except if they were feeling uncomfortably warm). Maybe these guys are
just extra testosterone-ey. <grin>

Welcome to the groups Kellyn and rats!

Yes it's normal for your rats to be constantly at each other especially
with a new chick around. ;)
Give them a few weeks and they will soon learn that the new girl is
never going into heat and this should calm them down some.
How old are the boys now?

They were born June 2, 2006, so that makes them a little over 7 months
old.

I'm sorry to hear about the rats, them being 7 months, its around that time
when their hormones are kicking in. I've had it with a few of my rats. I
looked into Tardak, with some conflicting opinions. Some rats it will work
with, some it wont, and you can only use it for a maximum of three months. I
didnt bother with it in the end. I think the fact that you have introduced
these rats when their hormones are raging is probably why they are like they
are. I persevered with mine, and only interfered if it got really nasty.
Fortunately, no blood was drawn, and only once did I have a rat come up with
an abscess. Thats something you will have to look out for, some cuts are not
visible, and can turn into abscesses quite quickly.

Interfering too much in squabbles can make rats frustrated, and more
aggressive, because the squabbles just dont reach a conclusion. At the
moment, it sounds like the newbie might be handling things better that what
you realise, if its coming out from hiding after the others have gone.

I havent had to get any of my males spayed, so far. The squabbles just
petered out after a while.

I totally agree with what jakewc2 has written.
Male rats can get tricky between the ages of 5 to 8 months. That's when
the hormones start raging... it should soon settle down though.
Another thing I wanted to add, cute little story:

In April, I adopted two older male rats from a rescue. The two together
seemed to be fighting a lot and lots of squeaking too. I was getting
upset because I thought these two were just not getting a long. One
night, the squeaking got so loud, I decided to pull the mean one out and
give him a piece of my mind. Of course he looked at me all innocent
like, blinking and staring... giving me these "I love you" looks...so I
put him back in the cage and I hid behind the couch.
Sure enough... the victim, runs up the ramp and jumps on the meanie,
meanie flips the victim over and victim screams bloody murder. Then they
stop, victim runs up the ramp and jumps down on the meanie...starting
the whole thing over again. Sheesh... he's not screaming bloody murder,
he's squealing in delight... boys!

Hehe, I forgot about the power grooming. Sometimes it does sound like they
are killing each other but that's all it is. Dominance and playfighting.

just wanted to update that the boys have stopped molesting hypatia and
all three have actually gotten along pretty well. i think she has been
a good influence on them as they also are not fighting nearly as bad as
previous. sorry for the typing. having to use on screen keyboard
because of no actual keyboard.

thanks for all the reassurances!

influence. lol
